COMBb2's Face Blur tool automatically detects faces in your photos and applies Gaussian blur or mosaic pixelation to protect identities. It uses AI-powered face detection running entirely in your browser - faces are never uploaded to any server. Essential for privacy compliance, street photography, real estate, and journalism.

Common Use Cases

  • Street photography
    Blur bystander faces to publish street photos without privacy concerns.
  • Real estate listings
    Obscure faces of people visible in property photos before publishing.
  • GDPR compliance
    Anonymize faces in images used in marketing, reports, or public-facing content in the EU.
  • Journalism and media
    Protect identities of sources, minors, or witnesses in published images.
  • Social media sharing
    Blur faces of others in group photos before posting online.

How It Works

The tool uses a lightweight face detection AI model running in your browser via WebAssembly. It identifies face regions in the image, then applies either Gaussian blur or pixelation over each detected face. You can adjust blur strength and choose between blur styles.

Why Privacy Matters Here

Face detection is inherently sensitive - faces are biometric data. Cloud-based face blur tools upload your photos (and the faces in them) to remote servers for processing. COMBb2 detects and blurs faces entirely on your device. No face data, no biometric information, and no photos ever leave your browser. This is critical for compliance with biometric privacy laws.

Frequently Asked Questions

Does it detect all faces in a photo?+
The AI detects most clearly visible faces, including those at various angles and sizes. Very small, heavily occluded, or extremely profile-angled faces may not be detected. Always review the result before publishing.
Can I choose which faces to blur?+
Currently, the tool blurs all detected faces. For selective blurring, process the image and then use an image editor to restore specific faces from the original.
What's the difference between Gaussian blur and pixelation?+
Gaussian blur creates a smooth, unfocused effect. Pixelation (mosaic) creates a blocky, low-resolution effect. Both effectively obscure identity, but pixelation is the traditional choice for news and media.
Is the blur strong enough to prevent identification?+
At default and higher blur strengths, faces are not identifiable by humans. However, no automated blurring can guarantee protection against all AI-based de-anonymization techniques. For high-stakes anonymization, consider combining face blur with metadata stripping.
Are the faces uploaded for detection?+
No. Face detection runs entirely in your browser. Your photos and the biometric face data never leave your device.
